APPARATUS EMPLOYED IN THE MANUFACTURE OF ARTIFICIAL SILK.

Specification of Letters Patent.

Patented Jan. 18, 1921.

Application filed August 26, 1919. Serial No. 320,020.

Be it known that I. Janus CLAYTON, a subject of the King of Great Britain, residing at 12 Middlesborough road, Coventry, in the county of 'arwick, England, have invented new and useful Improvements in Apparatus Employed in the Manufacture of Artificial Silk, of which the following is a specification.

This invention consists in an improvement in. or modification of, the invention for which I have made application, No. 309509, for Letters Patent dated the 9th day of July, A. D. 1919.

I have found that the utility of my invention. the subject matter of my said appli *ation X0. 309509, is improved if I cool the electric motors by which the spindles of the spinning nozzles are rotated to effect additional twisting between the said nozzles and the guides in the setting bath. such cooling not only preserving the motor. but also preventing any injurious effect of the heat of the said motors on the viscose, or the like. employed.

I effect this cooling of the motors by passing air. or causing air to pass. through them during their operation and I preferably utilize the standards which support the spindles and pumps. so that. while one serves for the passage of the viscose, or the like. the other serves for the passage of air to the motors. and I further. preferably. provide means for protecting. from viscose. or the like, and acid. these parts and the electric conductors by which cur rent is supplied to the motors.

The accompanying drawing represents what I consider the best means for carryiug my present invention into effect. but I do not limit myself to the precise details illustrated.

Figure 1 shows. in elevation partly in vertical section. Fig. 2 in sectional plan and Fig. 3 in section (partly in vertical section) at right angles to Fig. 1. suflic ent of the apparatus to illustrate the application of my invention thereto. I

The parts which correspond with those shown in the specification of my aforesaid application No. 309509 are marked with the same letters of reference, these parts being the spindle A. nozzles a, bath B, motor 7, f motor-casing G, ball bearings g, viscose-pipe H, for supplying the viscose, or the like,

mounted on the said pipe H. which is perforated to communicate with the passage 7' in the said standard, which passage is controlled by a valve j. The viscose. or the like, then passes through the trunnion to. and from, the pump K; by the passage at 7.1. through the filter L. and the other parts which arry the spindle A, of the nozzle,

and thence through the nozzle into the bath.

The other of the standards (J is mounted upon. and a passage j therein communicates with. a pipe I, into which air is passed, the interior of each motor-casing being put in communication with this pipe I. through the passage j", in the standard j which passage j", communi ates with a passage if, in the trunnion-piece 7c of the part L, which passage if, communicates with the space I, in the said part L; air, from the pipe I. passing through these passages j and 7:, into the said space Z, and thence, by the pipe 722, into the casing G, of the motor and between the rotor and stator of the said motor, and out by the opening 9 The course of the air is indicated bv the arrows. M

The motors are fed with electric current from any suitable source through conductors S. which are led through pipes s, to a switch at and thence to the stator f of the motor.

To protect the conductors and the parts beneath. I provide a guard-plate T, which may extend along the length of a machine of any number of spindles and has openings in it at z, for the passage and movement of the part L, of the spindle mountings when they are turned. and will allow any viscose, or the like. or acid, deposited thereon to flow of? without contaminating the parts beneath. or the conductors.

IVhat I claim is 1. In apparatus for spinning viscose or the like, a hollow spinning spindle through which viscose is passed, a motor for driving the same and comprising a rotor 011 the spindle and a surrounding stator. a casing inclosing said motor and the associated portion of the spindle, and means for passing a current of air through said casing and between the rotor and stator of the motor.

2. In a construction such as specified in claim 1, a hollow standard upon which the casing and nozzle are pivotally supported, and meansfor supplying air therethrough to the casing.-

3. In a construction such as specified in claim 1, a pair of hollow standards upon which the casing and nozzle are pivotally supported, and means for supplying viscose through one of the standards to the spinning spindle. and means for supplyingair through the other standard to the casing.

In apparatus for spinning viscose or the like, a setting bath trough, a hollow spinning spindle adapted to dip at its free end into the setting bath in the trough, a casing surrounding the opposite end of the spindle, a motor within the casing for drivingthe spindle, wire leads arranged below means for the casing and connected to the motor therein, a viscose feed pipe also arranged below the casing, and means for delivering viscose therefromto the spinning spindle, an air pipe arranged adjacent the viscose pipe, and delivering air therefrom to the casing to cool the motor, together with a drip pan overlying the wire leads, viscose feed means, and said pipes to protect the same from viscose and setting bath waste, in 'combination with a standard passing through said drip pan and supporting the spinning nozzle and motor casing above the latter, substantially as described.

In testimony whereof I have signed my name to this specification imthe presence of two subscribing witnesses.

. JAMES CLAYTON.
